Subtracting Side Chain
Inserting an external equaliser into the subtract side chain has the effect of
modifying the tonal balance of the processed signal by adding or subtracting a
specific band of frequencies. The external equipment should meet all the
requirements specified in the control side chain section (above) and be operated in
a similar manner. The adding or subtracting process requires that all signals are
appropriately phased and the gain be unity. Any errors may lead to unexpected
results.
For the units DE-ESS HF function, the internal filters have been phase and
amplitude corrected to achieve the required response.

.2 Repatching of the Barrier Strip for other uses and Special Effects
The following table lists many of the possible uses of the
DPR-402
. This is not an
exhaustive list, and other combinations may be tried. To obtain the full benefits of
its versatility, a simple understanding of how it works is required (
refer to section
13; Rear Barrier Strip
).

NORMAL COMPRESSION
Compression occurs equally at all frequencies.
D-G
C-B
H.F. RE-EMPHASISED COMPRESSION
Compression is higher at LOW frequencies. This
arrangement will make heavily compressed signals
sound brighter as it lessens the effect of heavy low
frequencies modulating the treble.
D-G
F-B
H.F. RE-EMPHASISED COMPRESSION
As above, but more pronounced.
F-G
F-B
L.F. RE-EMPHASISED COMPRESSION
Compression is higher at HIGH frequencies. This is
useful for controlling harsh or shrill components of a
signal, allowing faster ATTACK and DECAY to be
used before LF distortion becomes a problem.
D-G
E-B
L.F. RE-EMPHASISED COMPRESSION
Compression is higher at HIGH frequencies. This is
